If its getting warmer or more humid where you are this is probably a sign of needing to clean your outer coils. Remove the panel covering the compressor and check the condition of the coils. Clean with a nylon brush or wire brush. Or blow out with compressed air.

If the outer coils look OK see if they feel warm up and down the sides. If they don't you may have a defrost problem. If they are warm recheck them in 30 minutes if still warm or warmer and no one has opened the door check the lite inside, and the fan inside (it will only run with door closed). Hit the switch and see if lite goes out and make sure the switch is being activated with the door closed. And check the door seals any vinyl cracked on them they need replacing but can be warped sometimes letting in warm air (usually a sign of frost inside the door or water leaking out but not always).
It could be low on refrigerant or an inefficient compressor but not likely as much as these other items are.

The last thing is the thermometer could be reading wrong or out of calibration. Is it Electronic? Yes - Then its most likely one of the other problem before. If its mechanical (bi-metal) get another thermometer you trust or a new one and check it before you trust it. 2 of them telling you its 5'f then Id believe it other wise one or both of them are wrong.

If it's cutting off at too high a temperature it is a good possibility the probe is faulty. However if the compressor is not cutting off at all, suspect short of gas.

sounds like the compressor is not running. The condenser fans are located at the compressor. The fans in the conditioned space are the evap fans. A refrig usually does not have any device controlling the evap fans, they are to run 24/7. Freezers have other controls. Start there and let me know if I can help further.

What are your temp controls set to? If the controls are set to the max setting and it won't reach temp, you could have a broad range of problems ranging from bad door gaskets, to bad temp controls, to a low refrigerant charge, to possible a failing mechanical part such as a fan motor or compressor.

Freezer is too cold (-14 degrees) and fridge is too warm (51 degrees). The freezer keeps gettting colder but the fridge part keeps getting warmer.


The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.


The temp sensor for the freezer may be reading the warm air in the fridge so is not cutting the compressor off.

Our 4 year old GE side by side frig suddenly warmed to 64 degrees. Freezer stopped freezing and is at 43. Motor is running.


Really need to know what motor(s) are running (compressor, evap fan inside freezer compartment, condenser fan under fridge)?? Of course, check your temperature (thermostat) settings. Side-by-sides usually have 2 of them. They should be labled for refridgerator and freezer. The freezer control usually only opens a baffle from the freezer compartment to the refridge compartment. The refrigerator temp control is the one that controls the compressor on-off cycles and the temp of refrig compartment (this keeps the refrig compartment from freezing the milk and cokes) If the freezer control/baffle is set too far open, this will cause the refrig temp control to shut off too soon for the freezer temp to get low enough. These controls can get bumped out of the correct setting accidently from time to time.
To check the following, the fridge has to be running, or in a condition where it "should be" running: If compressor is running (condenser fan should be too), check if evaporator fan (inside freezer) is running. Open (freezer) door and hold door light switch in when you check evaporator fan operation (some fans stop when door is open) If it is not running you may have a bad evaporator fan motor. It could also be a bad defrost timer, causing the evaporator (also inside back of freezer) to ice-up. This blocks the air flow over evap. Also, there is a defrost terminator switch on the evaporator coil that stops the defrost cycle when coil is clear of ice/frost (but timer hasn't ended defrost cycle). If it is defective, that could also keep the fridge from going into the defrost cycle, or taking it out too soon. If it is the timer, change the defrost terminator as well. Depending on how handy you are, you may be able to check/change any of these parts yourself. If you don't know much about elecrical stuff, you should leave it to a repair tech. Hope this helps.

Freezers have a fan delay control that keeps fans off till coil reaches 25 *F.

GE 25 side by side refrigerator ice maker problem


Assuming the temp inside the freezer is at around 0 or -2 degrees, it should dump ice every ~50 minutes or so. Again, depending on temp's, an Ice Bin should fill within 24 to 48 hours. If your freezer temp is running at around 10 degrees, everything will obviously still be frozen (below 32), but the ice maker will take longer to freeze the water than it would if it were at 0 degrees. Open both doors and place the palm of your hand on the partition between the freezer and Fresh Food compartments... (where the door gaskets seat when they're closed). The temp of the partition should be about 5 or 10 degrees warmer than body temp., If it's hotter than that, you found the problem. Either the condenser coils are dirty and need a good cleaning OR your condenser fan motor (the fan in back, near the floor in the compressor area) is failed or about to fail.
